The influence of physiological state on the behavior of released laboratory-cultured Ceratitis capitata (Wiedemann) flies was evaluated after their arrival on four commonly-used odor-baited traps hung in a potted host tree in a field cage. Three-day-old and 12-day-old protein-deprived females and males were significantly more inclined than 3-day-old and 12-day-old protein-fed females and males to enter protein-odor-baited McPhail and Heath-Epsky traps. There was little or no influence of physiological state on propensity of flies to enter trimedlure-baited Jackson or Nadel-Harris traps. Across all physiological states combined, 74, 64, 0 and 0% of arriving females entered McPhail, Heath-Epsky, Jackson and Nadel-Harris traps, respectively. Corresponding values for arriving males were 60, 59, 86 and 82%. We suggest that future research on protein-odor-baited traps should be aimed at enticing a greater proportion of alighting C. capitata flies to enter the trap.
